cavium: Add CN81xx SoC and eval board support
This adds Cavium CN81xx SoC and SFF EVB files. Code is based off of Cavium's Octeon-TX SDK: https://github.com/Cavium-Open-Source-Distributions/OCTEON-TX-SDK BDK coreboot differences: bootblock: - Get rid of BDK header - Add Kconfig for link address - Move CAR setup code into assembly - Move unaligned memory access enable into assembly - Implement custom bootblock entry function - Add CLIB and CSIB blobs romstage: - Use minimal DRAM init only devicetree: - Convert FTD to static C file containing key value pairs Tested on CN81xx: - Boots to payload - Tested with GNU/Linux 4.16.3 - All hardware is usable (after applying additional commits) Implemented in future commits: - Vboot integration - MMU suuport - L2 Cache handling - ATF from external repo - Devicetree patching - Extended DRAM testing - UART init Not working: - Booting a payload - Booting upstream ATF TODO: - Configuration straps Change-Id: I47b4412d29203b45aee49bfa026c1d86ef7ce688 Signed-off-by: David Hendricks <dhendricks@fb.com> Signed-off-by: Patrick Rudolph <patrick.rudolph@9elements.com> Reviewed-on: https://review.coreboot.org/23037 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: David Hendricks <david.hendricks@gmail.com>
